SCA COGEN 2, a 193 MW Natural Gas power plant in Sacramento County, California. Operated by SACRAMENTO MUNICIPAL UTIL DIST, commissioned 1997.
How SCA COGEN 2 compares
With 193 MW of capacity, SCA COGEN 2 ranks 77th among the 874 operating power plants Bywatts maps in California and 44th of the 190 operating Natural Gas plants in the state. It accounts for about 0.5% of California's operating Natural Gas capacity and 0.3% of all operating capacity in the state. Nationally it is the 545th-largest of the 1,185 operating Natural Gas plants in the database. Commissioned in 1997, it is older than 58% of the 859 operating California plants with a recorded commissioning year. Its operator, SACRAMENTO MUNICIPAL UTIL DIST, runs 14 operating plants in California totaling 2,070 MW. It shares Sacramento County with 38 other operating plants, including COSUMNES and FOLSOM.
EIA-860 lists 4 generators at the site with 193 MW of nameplate capacity, mainly natural gas fired combined cycle technology. Net generation was 639 GWh in 2024 (a 38% capacity factor), down 10% from 2022. Its generators came online between 1997 and 2001.

Weather peril exposure
SCA COGEN 2 is a 193 MW natural gas power plant in Sacramento County, CA, operated by SACRAMENTO MUNICIPAL UTIL DIST, commissioned in 1997. Sacramento County carries low modeled catastrophe exposure in the FEMA National Risk Index, scoring 1.1 of 5 at the 3rd national percentile. Earthquake is the leading peril, rated Relatively High by FEMA at the 90th percentile.
The Bywatts loss layer is calibrated to solar PV hardware, so it is not applied to a natural gas plant. The ratings below are the FEMA National Risk Index county hazard ratings for this location.
Sacramento County hazard ratings
| Peril | FEMA rating | National percentile | Peril score | Events per year |
|---|---|---|---|---|
| Earthquake | Relatively High | 90th | 4.6 of 5 | 0.12 |
| Wildfire | Relatively Moderate | 89th | 4.6 of 5 | <0.01 |
| Heat wave | Relatively Moderate | 43rd | 2.7 of 5 | 7.0 |
| Riverine flooding | Relatively High | 36th | 2.5 of 5 | 1.9 |
| Hail | Relatively Low | 11th | 1.5 of 5 | 0.07 |
| Tornado | Relatively Moderate | 11th | 1.4 of 5 | 0.12 |
| Lightning | Relatively Moderate | 1st | 1.0 of 5 | 8.1 |
| Winter weather | Very Low | 1st | 1.0 of 5 | 0.06 |
| Strong wind | Very Low | 0th | 1.0 of 5 | 0.03 |
Perils not assessed in Sacramento County
These perils carry no usable National Risk Index figure for this county, so they are excluded from the scoring rather than scored zero. A zero would claim the peril was assessed and found benign.
| Peril | Why it is not scored |
|---|---|
| Hurricane | FEMA rating is "Not Applicable" for this county |
| Coastal flooding | FEMA rating is "No Rating" for this county |
| Ice storm | FEMA rating is "Not Applicable" for this county |
